[A mother, a father, and their little daughter Amy are walking through an airport.  Suddenly, Amy begins running towards John McCain.]

Amy:  Grandpa!  Grandpa!
McCain:  Hello--Julie?

[Amy turns white as a ghost.]
[Joe Lieberman leans over and whispers into McCain's ear.]

McCain:  Sorry.  You're Amy, right?
Amy:  (fearfully) Y-y-yes, Grandpa.
